Impact on society of a hardcore pornography

Berl Kutchinsky's Studies on Pornography and Sex Crimes in Denmark (1970), a scientific report commissioned by the Presidential Commission on Obscenity and Pornography, found that the legalizing of pornography in Denmark had not (as had been expected) resulted in an increase of sex crimes.

A study conducted in Denmark in 2003 and later published in Archives of Sexual Behavior found that Danish men and women generally believe that hardcore pornography has a positive influence on their lives.
